1- What do you mean "able to control message size"? Is it max-pending-spout
parameter?
By using for example Kafka as your source of information of the benchmark
topology, you may produce i.e. control the size of messages in terms of bytes
length. Why would you want to do this? Because there is a relation between
certain performance characteristics such as throughput and message size.
Is there any published benchmark like this old-one here:
As far up to my knowledge, no. However, we at the Web Information Systems
research group of the Delft University of Technology are currently in the
process of benchmarking several streaming engines (including Storm) part of an
empirical research. If you’d like to here more about the insight so far
gathered, feel free to email me.

Well, this depends onto the aspects of the measurements.
You may for example define a topology consisting of a spout, transformation
bolt and sink that receives byte arrays from Kafka, transforms them and
outputs. The nice thing is that you’d be able to control for the size of the
messages.
In addition, if you care about the performance in conjunction to stateful
operations such as aggregations, your topology might look alike the for example
WordCount topology.

Hi Dominik,
Many thanks for details. Actually I am looking for a set typologies for my test.

Hi Walid,
You may benchmark Storm’s performance in terms of throughput and end-to-end
latency for example. In addition, the investigation could also include
variances in the configurational settings, such as the parallelism, message
size, intra-worker and inter-worker buffer size which some of them have a
profound effect onto the performance of Storm.
There are already a few benchmarks of Storm’s performance such as:
https://developer.ibm.com/streamsdev/wp-content/uploads/sites/15/2014/04/Streams-and-Storm-April-2014-Final.pdf
In addition, you may want to take a look at the academic paper Storm@Twitter
and Twitter Heron: Stream processing at scale which describe among others
certain performance aspects of Storm that might be helpful to you when
designing the benchmark.

Hi Everyone,
Anyone please could tell what are the common benchmarks for testing Storm
performance?
Thank you,--Regards
